This is a video sent to me by Marc Holdereid of Bristol University, who I've been talking to about bats and how we can interpret what they 'see' from their echo-location calls. They have a idea of their environment from the return sound of their clicks, so how does this work?? Can they see this in their 'minds eye' or... obviously they are not as visually focussed as we are. This visualisation is based on analysis of their echo-location calls, recreating a flight path, and is not a visual recording. Watch closely, and the environment 'fades' as the return sound of the echolocation call dissipates...
Awesome... (by the way, the bat was flying along a gap between some trees, where a fence had been put in... its pretty clear in the video when you know that)
